The Railway Museum (Dutch: Het Spoorwegmuseum) in Utrecht is the Dutch National Railway Museum.
It was established in 1927 and since 1954 has been housed in the former Maliebaan station. The museum currently owns a large and varied collection of rolling stock.

Tank Wagon NS 515615 P built in 1919 by Wagonfabrik Uerdingern D and preserved at the Het Spoorwegmuseum / Railway Museum in Utecht Maliebaan former Station. July 15th, 2022.

The car was part of a series of tank cars for internal transport of the Staatsmijnen (SM) and originally had the number 10402 there. Later it was admitted to the main network of NS and was given the new number NS 515615 P (P from private person, so no NS property). In 2008, the all-black car was given the inscription Staatsmijnen - Creosote Oil in large letters in the railway museum.
Creosote was used, among other things, to impregnate wooden sleepers.
